Background
In Greece, HIV/AIDS surveillance is based mainly on the case reporting system, which, however, is affected by patterns of testing and reporting. Specific information on the prevalence and incidence of HIV disease is required for an effective and well-planned response to the epidemic. The Estimation and Projection Package (EPP) is a software developed by UNAIDS and partners, which assists countries to map their HIV epidemic on the basis of available HIV prevalence data. The aims of the present study include: i) the systematic review of Greek and international literature in order to retrieve relevant HIV prevalence studies carried out in Greece, and ii) the use of the extracted prevalence estimates in EPP to produce the Greek epidemic curve.
